Canon EF 40mm f/2.8 STM Pancake

The Canon EF 40mm f/2.8 STM Lens is a unique and indispensable addition to Canon's series of EF lenses. The EF 40mm f/2.8 STM offers an ultra-slim and lightweight design. Incredibly compact in size, the EF 40mm f/2.8 STM delivers high image quality from the center to the periphery thanks to its advanced lens configuration including an aspherical element, a bright 2.8 aperture, and optimized coatings that minimize ghosting and flare while providing exceptional color balance.
The EF 40mm f/2.8 STM's unobtrusive design helps the photographer avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations with no compromise in performance.
